Demand Planning & Shaping

Trade offs The Fresh Connection is full of trade offs Over multiple roles and within roles Sometimes conflicting with role incentives Capacity mgt Demand mgt Supplier mgt Inventory mgt Demand shaping Demand forecasting

Promotion effect P D lead lag Promotion peak baseline Promotion: Extra sales effect in time frame of a few weeks by extra discount to retailer/consumer and communication Promotion low Baseline = Regular sales without promotions Liftfactor= promotion peak/baseline Dipfactor= promotion low/baseline Netto effect= surface P – surface D

Promotion effect - consumer and retail effect lead lag R= retail effect; goods flow from supplier to retailer C= consumer effect; goods flow from retailer to consumer PR PC DC Promotion peak DR Baseline Promotion low Liftfactor= promotion peak/baseline Dipfactor= promotion low/baseline Netto effect= surface P – surface D (=Pr-Dr=Pc-Dc)

Promotion effect - implications for the supply chain Additional sales P Forward buying or cannibalisation D Promotion peak Baseline Promotion low Supply Chain must first increase and afterwards decrease output to keep synchronised with sales. Part of the additional sales is only a shift in time.

Involvation Training - Tactisch Voorraadbeheer The need for a forecast 28-4-2017 stock demand De eenvoudigste vorm van vraagvoorspelling is uitgaan van de historische vraag als verwachte vraag Wanneer de vraag redelijk constant en continu is, vormen historische verbruikscijfers voldoende basis voor voorraadbeheer. Vaak zijn vraagpatronen minder constant. Parameterbepaling (bestelpunt en –hoeveelheid) op basis van verbruikscijfers kan dan tot ongewenste resultaten leiden (zie figuur). Beschikt u over kennis en/of informatie met betrekking tot de ontwikkeling van de vraag, b.v. trend, seizoensfluctuaties, cyclische patronen en/of actie? Dan is het verstandig om meer aandacht te besteden aan vraagvoorspelling. Met vraagvoorspelling wordt normaliter bedoeld de voorspelling van de onafhankelijk vraag voor voorraaditems. tijd Supply en Demand Management

Quality of forecasting Involvation Training - Tactisch Voorraadbeheer Quality of forecasting 28-4-2017 The bias: average deviation forecast en demand over a longer period The mape: absolute error (%) per time-bucket U kunt met vraagvoorspelling de schattingsfout reduceren, d.w.z. de mate van variabiliteit van de werkelijke vraag ten opzichte van de geschatte vraag (μ). Het resultaat van een goede vraagvoorspelling is dat de benodigde veiligheidsvoorraad afneemt. Explore TFC What is the Mape and Bias per finished product? Supply en Demand Management
